An anti-disturbance center-driving sludge scraper is provided. The sludge scraper comprises an operating bridge, a sludge scraping shaft, a motor, a reducer, a bearing base, a stream guiding barrel, water feeding pipes, scraping arms and sludge scraping plates. Two ends of the sludge scraping shaft are respectively mounted at the center of the operating bridge and the bottom of a sedimentation tank through bearings. The motor and the reducer are disposed on the operating bridge. The output end of the reducer is connected to the sludge scraping shaft through a coupler. The stream guiding barrel is fixed below the operating bridge. Water discharging ends of the water feeding pipes penetrate the side wall of the stream guiding barrel, are in the cavity of the stream guiding barrel, and are provided with bends. A water baffle disc is fixed in the cavity of the stream guiding barrel through fixing arms. At least three guide pillars are fixed above the water baffle disc and are sleeved with springs and a buffer disc. The buffer disc is disposed above the springs and below the water feeding pipes. The upper ends of the guide pillars are provided with stop blocks. The sludge scraping shaft penetrates the water baffle disc and the buffer disc. According to the sludge scraper, impact of jet-flow sewage to the stream guiding barrel is reduced, the service lifetime of the stream guiding barrel is prolonged, and bottom sludge disturbance of the sedimentation tank caused by the sewage is reduced.
Description
technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an anti-disturbance central drive mud scraper. Background technique [0002] The mud scraper is mainly used in circular sedimentation tanks with large diameters in urban sewage treatment plants, waterworks and industrial wastewater treatment to remove the sludge settled at the bottom of the tank and skim the scum on the surface of the tank. [0003] The current stabilizing cylinder of the existing mud scraper is generally a straight cylinder structure, which is easily agitated by the water flow of the inlet pipe to float the underwater sludge, which is not conducive to sludge sedimentation. [0004] The Chinese patent No. CN203017812U discloses a new type of steady flow cylinder. A feed pipe is arranged on the upper part of the cylinder body. The transmission shaft of the mud scraper passes through the cylinder body. The feed pipe is arranged on the side wall o...
